. Abpucationhlea octoberzl, 1 918. serialneeeaossp To all whom t may concern:

Be it known that I, ZACHARYYKUTCHK, a subject ofthe Government of Russia re-v siding vat Southwest, in the county of Westmoreland andState of Pennsylvania, have invented certain new and useful Improvements in Spring-Tires, of which the,v following is a specification. i

This invention relates to'improvements in spring tires and the primary object thereof is to provide a tire of the type set forth whereby theuse of rubber isentirely eliminated. y

Other objects of this invention are to provide a tire of the character described which is simple in its construction and arrangement, strong, durable and eliicient in its use and inexpensive to manufacture.

To the accomplishment 0f these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing wherein is shown an embodiment of the invention.

In the drawing, forming a portion of this speciication and wherein like numerals of reference designate corresponding parts throughout the several views:

Figure 1 is a transverse view of one unit partly in section.

Fig. 2 is a side view lthereof.

Fig. 3 is a top view of one of the tread links, and Fig. 4 a side view thereof.

Figs. 5 and 6 are side and top views, respectively, of one of the supporting links.

Figs. 7, 8 and 9 are views illustrating the construction of one of the clamping plates.

The spring tire is constructed from a plurality of sections each consisting of the supporting link 1, the coils 2 and 3 securely fastened thereon by the clamping plate 4, the supporting bar 5 connected to the ends 15 of the coils 2 and 3, and the three parallel tread links 6 secured to the supporting bar by the rivet 13 which passes through the lugs 14 of the supporting bar 5.

The tread links 6 are made preferably from blocks of metal and are provided at one end with the ears 7, and at the other with the lug 8. The ears 7 and the lug 8 are partially formed by the recesses in the tread link 6 as shown at 9 and 10, respectively.

The ears 7 and the'lugs 8 are interitting to form a continuous chain and are formed toward the inner portion ofthe tread link to allow agreater wearing thickness. 1Apertures 12 and 11 are provided in the ears 7 and.A lugs 8,l respectively, for Vthe reception of rivets for connecting the tread links together in a manner hereinafter described. In forming the tread `for the tire, three chains formed by the links as abovedescribed are runparallel-to each other and 13 which pass through-the lugs -14 of the supporting bars. s It willbe noted that.

`the rivets 13 not onlyn connect the parallel drawing.

The supporting links 1, provided with the ears 17 and the interfitting lugs 18, and secured together to form a chain by the rivets 19, in apertures 20 and 21, entirely embrace the periphery of the wheel rim 22. The Vlugs 18 are of less width than the recesses or spaces between thel ears 17 topermit the insertion of the lugs 24, of the clamping plates 4, in a manner hereinafter described. The top of each link 1 has two grooves 23, which conform in curvature to the inner portion of the coils 2 and 3 which are seated therein, as shown in Fig. 2 of. the drawing.

The coils 2 and 3 are securely held within the grooves 23, of the supporting link 1 connected together Vby means of the rivets ears 17 andthe lugs 18, respectively. After with t-he corrugations 26 so as to conform to the contour of the coils 2 and 3 over which it is placed, as clearlyishown in Fig. 2 of the drawing.

The supporting bar 5 has a rounded inner portion 27 to accommodate the movement of the coils 2 and 3 therein. The outer portion 28 is Hat and forms the seat for the tread links 6 which are mounted thereon between the lugs 14.

It will be obvious that a tire constructed from sections as herein described will be resilient and flexible, and may be placed around the tire rim and secured thereto in any desired manner.

From the foregoing description taken in connection with the accompanying drawing the construction and application of my improved tire will be readily. apparent without a more extended explanation, and it is to be understood that various changes in the form, proportion and in the minor details of construction may be restored to as come within the scope of the claim hereunto appended.

What I claim as new and desire to secure yley-Letters Patent vis:- A

A springtire comprising a plurality of supporting links flexibly riveted together, spring coils mounted on each of said supporting links, a clamping plate for securing said coils to each of said supporting links, supportingbars carried by the said coils, and a tread chain pivotally mounted in the said supporting` bars and consisting of three parallel rows of tread links flexibly riveted together, substantially as described and for the purpose set' forth.

In testimony whereof I afliX my signature.
